INSTALLER INFORMATION
FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD
CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.
WARNING: OUT OF PHASE TRANSFORMERS
On two transformer systems, the transformers MUST be
in phase. Measure the voltage across RC and RH. If more
than 12 Volts AC is present between RC and RH, then the
transformers are NOT in phase.
To correct this condition, reverse the secondary low
voltage connections at either the Heating or Cooling
transformer.
VOLTAGE REQUIREMENTS
Do not use on circuits exceeding specified voltage. Higher
voltage will damage control and could cause shock or
fire hazard.
Thermostat installation and all components of the control system
shall conform to Class II circuits per the NEC code.
